Another common desalination process is Reverse Osmosis. It involves a solvent passing through a semi-permeable membrane; meaning this particular membrane only allows some molecules to penetrate or pass through. The solvent will then go into a solution with higher concentration of molecules.
Most genetically engineered fish are used in basic research in genetics and development. Two species of fish, zebrafish and medaka, are most commonly modified because they have optically clear chorions (shells), rapidly develop, and the 1-cell embryo is easy to see and microinject with transgenic DNA.ome GM fish that have been created have promoters driving an over-production of all fish growth hormone. This resulted in dramatic growth enhancement in several species, including salmonids, carps and tilapias.
GMO corn and soy help fight off bugs and are drought-resistant. GMO salmon grows faster to help raise much-needed fish for a growing population in need of healthy sources of protein. GMOs are one way to help solve world hunger.or instance genetically altered seeds that deter insects are beneficial because they allow crops to be grown without the threat of being destroyed by pest. The same goes for those that are altered to withstand colder or hotter temperatures. GMOs have their positive points.
